摘要:
Method for preparing a membrane from fibril cellulose includes supplying fibril cellulose dispersion on a filter layer, draining liquid from a fibril cellulose dispersion by the effect of reduced pressure through the filter layer that is impermeable to fibrils of the fibril cellulose but permeable to the liquid to form a membrane sheet on the filter fabric, applying heat on the opposite side of the membrane sheet to the membrane sheet while continuing draining of the liquid through the filter layer by pressure difference over the filter layer, and removing the membrane sheet from the filter layer as a freestanding membrane.
摘要(中):
从原纤维纤维素制备膜的方法包括在过滤层上提供原纤维纤维素分散体,通过减压的作用将来自原纤维纤维素分散体的液体排出通过过滤层,所述过滤层对原纤维纤维素的原纤维是不可渗透的,但是对于液体可渗透至 在所述过滤织物上形成膜片,在所述膜片的相对侧向所述膜片施加热量,同时通过所述过滤层上的压力差使所述液体通过所述过滤层排出,并且从所述过滤层除去所述膜片 作为独立膜。
